Code Samples on NodeJS Module.Exports

This article represents code samples on NodeJS Module.exports. Please feel free to comment/suggest if I missed to mention one or more important points. Also, sorry for the typos.

Code Sample for a NodeJS Module using Module.Exports

Save the code as “room.js”.

module.exports = {
  
  windowsCount: 0,
  doorsCount: 0,
  LARGEROOM: {doorsCount: 2, windowsCount: 2},
  SMALLROOM: {doorsCount: 1, windowsCount: 1},
  
  getDoorsCount: function () {
    return ++this.doorsCount;
  },
  
  getWindowsCount: function() {
    return ++this.windowsCount;    
  }, 
  
  isLargeRoom: function(config) {
    if(config.doorsCount >= this.LARGEROOM.doorsCount && config.windowsCount >= this.LARGEROOM.windowsCount) {
      return true;
    }
    return false;
  },
  
  isSmallRoom: function(config) {
    if(config.doorsCount <= this.SMALLROOM.doorsCount && config.windowsCount <= this.SMALLROOM.windowsCount) {
      return true;
    }
    return false;
  }
  
};

Code to Execute Module

Following code could be used to execute above module using command such as “node main.js”. Save the file below as “main.js” in the same folder as “room.js”.

var r = require("./room.js");
console.log("Total no of doors: " + r.getDoorsCount());
console.log("Total no of windows: " + r.getWindowsCount());

var roomSize = r.isLargeRoom({doorsCount:2, windowsCount:3});
console.log(roomSize === true?"Large room":"Small room");

Above will print “Large room”.
